T0 all whom t may concern:

Be it known that I, LUD HOLLAND-Lum,

a citizen of the United States, residingaty Chicago, in the county of Cook and State of Illinois, have invented certain new and usegear is usually secured to the traction wheel v in a manner to rotate therewith. Substantially all traction wheels of the class indicated are now. made wholly of steel and malleable iron, the hub portion thereof consisting of separable rings to which the inner ends of the spokes are connected. A removable sleeve is received by axial'openings in the rings and the main driving gear is s'ecured to the rings.

This invention consists in providing an improved form of sleeve and hub rings and in the manner whereby the main driving gear is secured to the rings, permitting the sleeve and axle to be separated from the wheels for safety in shipping; the object of the invention being to provide a mechanism that may be readily and quickly assembled with the associated parts in operative relation, and for shipping purposes the parts may be quickly separated. These objectsare attained by means of the mechanism illustrated by the accompanying drawings, in which- Figure l represents a vertical sectional' View of part of a harvester traction wheel having my invention forming a part thereof; Fig. 2 represents a side elevation of part of Fig. 1, and designed to illustrate the manner of attaching the main driving sprocket to the wheel and the construction and application of a sectional Washer forming part of the mechanism; Fig'. 3 is a cross section of one ofthe'hub rings to which the inner ends of thespokes are attached; Fig. 4 is a side elevation of Fig. '3; Fig.y 5 is a cross seetion of :the hub ring to which the main sprocket wheel is secured; Fig. 6 is a side elevation of Fig. 5; Fig.' 7 is a. top plan view of a special form of washer forming part of the mechanism shown in Fig. 1; Fig. 8 is a side elevation of Fig. 7; Fig. 9 is a plan view of one of the parts of a sectional washer in the plane of its thickness; Fig. 10 is a side elevation of Fig. 9; Fig. 11 is a plan view of the other part of the sectional washer in the plane of its thickness; Fig. 12 is a side elevation of Fig. 11; and Fig. 13 is an yend eleva?- tion on an enlarged scale of the hub sleeve.

The same parts lare designated by like reference characters throughout the several views. f

a 1 represents the wheel rim having the outside ends of't'he spokes 2 secured thereto; 3 a hub ring to which is secured the inner ends of the spokes upon one side of thefwheel; 4 a hub ring to ywhich the spokes upon the opposite side of the wheel and a main driving spocket wheel- 5 are secured by means of bolts 6. represents an axle upon which the wheel 1s Journaled by means of a removable sleeve 8, the sleeve being provided at opposite ends thereof with roller bearings 9 engaging with the axle.

In harvesting machines the axle is usually provided with pinions that are secured to opposite ends thereof. The sleeve is cylindrical in form and provided near one end thereof with a circumferential flange 11 that forms a bearing for an internall annular flange 12 forming part of the hub ring 3, and on the opposite end thereof with other circumferential lianges 13 and 14 spaced apart and forming bearings for an internal annular flange 15 upon theihub ring 4 and for the sprocket wheel 5, respectively.

16 represents short radially arranged wing members arranged parallel with the axis of the sleeve at an angleof 90 apart, and having one end thereof joining the inside of the flange member 11, and the wings extending beyond the periphery of the flange, and 17 represents other wingmembers radially arrangedbetween flanges 13 and 14 in line with said lirst mentioned wings and extending beyond the periphery of said flanges.

The annular flange 12 uponvthe. hub ring 3 is provided with radially arranged notches 18 that permit the wing members 16 to pass therethrough when the sleeve is being passed through the hub ring, and like radially arranged notches 19 are provided in the annular flange 15 of hub ring 4 that permit the wing members 17 to pass therethrough. When the sleeve is passed through the hub rings and the wings thereon have passed through the notches and slightly beyond them, it is turned axially until said wings are at intermediate points between the 11o yso notches and opposite the openings between the raised rib portions 191 onthe annular flanges when the sleeve is pulled in a reverse direction to seat the ends of the wings against the annular flanges, and at the same time lock it against independent rotation by reason of its engagement with the raised rib portions 191.

rlhe hub ring 4: is provided with a series of tranverse openings 2O through the vllange 15, and the main driving sprocket wheel 5 is provided with a like series of openings that receive the bolts G in a manner whereby the hub ring and the sprocket wheel are securely clamped against opposite ends of the wing members 17, thereby securing the sleeve in position. ln order that the bolts G may be secured from the outside of the wheel, paired lugs 192 are provided upon the inner side of the ring t to position the heads of the bolts.

21 represents an oil duct extending through the wall of the sleeve and communicating with the chamber 22 surroundg ing the axle. 221 represents similar flanges at opposite ends of the chamber that separate it from the roller bearing cages 23, the flanges being provided with a series oi radially arranged notches 24 forming oil ducts communicating with the chamber and the bearing mechanism.

25 represents a special form of washer having an axial opening 26 to receive the axle, and a laterally projecting rim 27 that overlaps the end of the sleeve, the rim having a widened portion that is provided with a radially arranged notch 28 that receives the end of a wing 29 integral with the sleeve in a manner to cause the washer to rotate with the wheel.

30 represents pinions secured to the opposite ends of the axle, and 31 a sectional washer interposed between the pinion and other washers 321 upon the axle and contacting with Washers 25 and 31.

rlhe sectional washer is made in two parts, 32 and 33, semicircular in form and joined on a dianietrical line, the part 32 being provided with ear members 3a that are'adapted to overlap the part 33 and provided with openings 35, and the part 33 is provided with a hook 36 that is adapted to be received by the opening in one of the ear members in a manner to form a hinge connection between the two parts of the washer. Each partis provided with a semicircular notch concentrically arranged to form an axial opening adapted to receive lthe axle when placed in position thereon, and a bolt 37 secures the two parts in operative relation. Part 33 is also provided with a radially arranged wing portion 38 that is provided with an opening therein that is adapted to receive the hooked end of a link 39, and the opposite end of the link may be connected said rings and said sleeve.

with a fixed part of the harvester in a manner to prevent the washer from rotating with the wheel. The part 33 is also provided with a radially arranged oil duct 40 that conducts lubricant to the bearing surfaces of the washers.

lWhen the assemblage of parts is complete the opposite end ot the axle is provided with a pinion and a duplicate series of washers. `When it is desired to remove the sleeve the sectional washer at that end carrying the sprocket wheel is removed and the clamping bolts released, the sleeve is turned axially until the wings thereon register with the notches in the annular flanges in the hub rings, and then the sleeve may be withdrawn from the hub rings.

W'hile l have in this application described one embodiment which my invention may assume in practice, it is, of course, to be understood that the form shown is used vfor purposes of illustration and that the invention may be embodied in other forms without departing from its spirit.
